Whosoever disturbs the public peace, or obeys not the laws, that is, the conditions under which men bear with and defend one another, ought to be excluded from society, that is, to be banished from it. Whosoever will read with a philosophical eye the codes and annals of different nations will find almost always that the names of virtue and vice, of good citizen and criminal, are changed in the course of ages, not in accordance with the changes that occur in the circumstances of a country, and consequently in conformity with the general interest, but in accordance with the passions and errors that have swayed different legislators in succession. He will observe full often, that the passions of one age form the basis of the morality of later ones; that strong passions, the offspring of fanaticism and enthusiasm, weakened and, so to speak, gnawed away by time (which reduces to a level all physical and moral phenomena) become little by little the prudence of the age, and a useful[204] instrument in the hand of the strong man and the clever. In this way the vaguest notions of honour and virtue have been produced; for they change with the changes of time, which causes names to survive things; as also with the changes of rivers and mountains, which form frequently the boundaries of moral no less than of physical geography. It has already been remarked by Montesquieu that public accusations are more suited to republics, where the public good ought to be the citizens first passion, than to monarchies, where such a sentiment is very feeble, owing to the nature of the government itself, and where the appointment of officers to accuse transgressors of the law in the name of the public is a most excellent institution. But every government, be it republican or monarchical, ought to inflict upon a false accuser the same punishment which, had the accusation been true, would have fallen upon the accused.

There seem to be three principal reasons why, under our present system, crime still keeps its general level, irrespective of all changes in our degrees of punishment. Yet, supposing it were proved to-morrow that punishment fails entirely of the ends imputed to it; that, for example, the greater number of crimes are[80] committed by criminals who have been punished already; that for one chance of a mans reformation during his punishment there are a hundred in favour of his deterioration; and that the deterrent influence of his punishment is altogether removed by his own descriptions of it; shall we suppose for a moment that society would cease to punish, on the ground that punishment attained none of its professed ends? Would it say to the horse-stealer, Keep your horse, for nothing we can do to you can make you any better, nor deter others from trying to get horses in the same way?

Persons guilty of lesser crimes are usually either punished in the obscurity of a prison, or transported, as an example to nations who have given no offence, to a distant and therefore almost useless servitude. Since the gravest crimes are not those which men are tempted to commit on the spur of the moment, the public punishment of a great misdeed will be regarded by most men as strange and of impossible occurrence; but the public punishment of lighter crimes, to which mens thoughts more readily incline, will make an impression, which, at the same time that it diverts the mind from them, will restrain it still more from crimes of greater gravity. Punishments should not only be proportioned to one another and to crimes in point of force, but also in the mode of their infliction.

Torture, again, is employed to discover if a criminal is guilty of other crimes besides those with which he is charged. It is as if this argument were employed: Because you are guilty of one crime you may be guilty of a hundred others. This doubt weighs upon me: I wish to ascertain about it by my test of truth: the laws torture you because you are guilty, because you may be guilty, because I mean you to be guilty.

It is impossible to prevent all the disorders that may arise in the universal conflict of human passions. Their increase depends on that of population and on the crossings of private interests, which cannot be directed with geometrical exactness to the public welfare. In political arithmetic the calculation of probabilities must be substituted for mathematical exactness. Glance at the history of the world, and you will see disorders increase with the increase of the bounds of empire; thus national feeling being to the same extent diminished, the general inducement to crime increases with the greater interest of each individual in such disorders, and on this account the necessity for aggravating penalties ever continues to increase.

It would, therefore, be a mistake to ascribe to one, who only discusses social conventions and their consequences, principles contrary either to natural law or to revelation, for the reason that he does not discuss them. It would be a mistake, when he speaks of a state of war as anterior to a state of society, to understand it in the sense of Hobbes, as meaning that no obligation nor duty is prior to the existence of society, instead of understanding it as a fact due to the corruption of human nature and the want of any expressed sanction. It would be a mistake to impute it as a fault to a writer who is considering the results of the social compact[115] that he does not admit them as pre-existent to the formation of the compact itself.

Neither the noble nor the rich man ought to be able to pay a price for injuries committed against the feeble and the poor; else riches, which, under the[206] protection of the laws, are the prize of industry, become the nourishment of tyranny. Whenever the laws suffer a man in certain cases to cease to be a person and to become a thing, there is no liberty; for then you will see the man of power devoting all his industry to gather from the numberless combinations of civil life those which the law grants in his favour. This discovery is the magic secret that changes citizens into beasts of burden, and in the hand of the strong man forms the chain wherewith to fetter the actions of the imprudent and the weak. This is the reason why in some governments, that have all the semblance of liberty, tyranny lies hidden or insinuates itself unforeseen, in some corner neglected by the legislator, where insensibly it gains force and grows.

Wise governments suffer not political idleness in the midst of work and industry. I mean by political idleness that existence which contributes nothing to society either by its work or by its wealth; which gains without ever losing; which, stupidly admired and reverenced by the vulgar, is regarded by the wise man with disdain, and with pity for the beings who are its victims; which, being destitute of that stimulus of an active life, the necessity of preserving or increasing[222] the store of worldly goods, leaves to the passions of opinion, not the least strong ones, all their energy. This kind of idleness has been confused by austere declaimers with that of riches, gathered by industry; but it is not for the severe and narrow virtue of some censors, but for the laws, to define what is punishable idleness. He is not guilty of political idleness, who enjoys the fruits of the virtues or vices of his ancestors and sells in exchange for his pleasures bread and existence to the industrious poor, who carry on peacefully the silent war of industry against wealth, instead of by force a war uncertain and sanguinary. The latter kind of idleness is necessary and useful, in proportion as society becomes wider and its government more strict.
